If you or your partner requests to end the game, who do you tell to have it archived? Because I'd still like to access the posts for late reference, but I don't want it clogging space in the actual category it happens to live in right now. Can someone help me?

Completed games are for games that have reached a literary conclusion. If someone were to read it from start to finish, they would come away with the impression that it was a complete 'thing in itself'. A game where one or more parties simply decides that the story won't be continued stays in the board that it was started in, and gradually drifts off into the deeper pages.
